Yes, especially when the poster NEVER posts anything else. Never goes to any other threads and posts personal anecdotes or engages with other people here. There are scammers who spend all day and night compiling info on people, hoping to match it up with info for identity theft that they bought on the black market. OR hoping to get enough info to call or email you to get money, account numbers, etc., from us. They can just possible cull the info people post on their threads waiting for some relevant info they may be able to use. The DIS is Googleable. And we have our own Search button once someone gets here. The other say, some new member found and bumped up a thread from 12 years ago. So, the archives here go back quite a ways.
Some nefarious persons can gather quite a personal profile on a person who posts on their thread and posts other personal stuff on other threads here and go to town with identity theft, creating another you that has a lot of the real info some of you gave HERE: city you live, approximate date of birth from ascertaining when you were conceived, (for some the year, since you mentioned your age in another thread,) the age of your parents and if still alive and where were they born, the age of your grandparents and if they are still alive, and where were they born, their ethnicity, the number of siblings you have and their ages, the number and ages of children you have, their names, their interests, your occupation, your interests, where else you vacation, the list goes on & on and on.
EACH of us, when we use the internet have an individual IP address. Most times when you visit a website, it can log in your IP address as well as your location, down to the block you are on, if not the exact building, like Google Maps does. Ever go to Fandango looking for a movie to watch in your city, and it knows your zip code even before you input it? I have my Google, Microsoft and Firefox set to NOT use my location for sites, yet, various sites still end up getting it.
Check for yourself. Go to Google and type in:
"What's my IP address?"
There will be a list of about 10 websites that will tell you your IP address as well as the city, and on some, the block you live on or your zip code, IF you aren't using the Internet via an VPN server which masks your IP address by funneling your stuff through their own servers and then their IP address is used instead. (Or something like that.)
